@juliadunavant, what version of the Mac OS are you currently running? If you are running anything lower than El Capitan, you need to try to update to either El Capitan or High Sierra. There is a thread here in the Mac section that details all of this.
EA/Maxis is aware of the issue and is working to fix it. A patch should be out soon.
